Provided is a deck fixing apparatus including a rectangular support plate having a bottom surface which can partially come into contact with the top surface of a lower support; deck fixing parts formed by pressing the both side portions of the support plate and each of the deck fixing parts having a top surface for supporting the bottom surface of a deck and piece-fastened to the deck; and a support fixing part formed by extending a part of one side end of the support plate outwards in a plate surface direction so as to be fixed to the lower support, wherein the support plate has a cutout formed by cutting out a predetermined area inwards at the other side end of the support plate. Therefore, such deck fixing apparatuses can be coupled to each other in an angle-adjustable manner, thereby enabling the curve section construction of decks.
